Idaho — Snow-covered highways and muted mountain views greet travelers this Christmas morning as winter tightens its grip across central Idaho. Visibility drops at times, and tire spray fades into swirling flakes near higher elevations.
A Winter Storm Warning remains in effect through late afternoon for the Sun Valley Region and the Big Lost Highlands, according to the National Weather Service in Pocatello. Additional snowfall up to 4 inches is expected, with the highest amounts focused near Galena Summit and higher-elevation backcountry areas.
Road conditions remain the primary concern. Snowfall continues on already cold pavement, creating slick stretches along Highway 75, especially between Ketchum, Galena, and Sun Valley. Drivers heading toward Copper Basin and the Big Lost Highlands should be prepared for reduced traction and slower travel through the afternoon.
While snowfall rates are not extreme, persistent light snow makes conditions deceptive. Roads may appear passable but can turn icy quickly, particularly in shaded mountain corridors. Plows are active, but accumulation continues faster at elevation.
Travelers are urged to plan carefully. According to the National Weather Service, those who must drive should carry extra food, water, and a flashlight in case of delays. Checking 511.idaho.gov before departure is strongly advised, as conditions can change quickly through the day.
Snow tapers later this afternoon, but impacts linger into the evening as temperatures stay cold. Clearing skies do not guarantee safer roads right away, especially where packed snow refreezes after sunset.
Looking ahead, quieter weather is expected later tonight, offering some improvement for post-Christmas travel. Still, winter driving conditions remain a factor across mountain passes.
Drivers should slow down, allow extra stopping distance, and avoid unnecessary travel until conditions improve. The Winter Storm Warning remains in effect through this afternoon, and additional advisories are possible if conditions persist longer than expected.
